Abstract

PURPOSE: To stably supply the voltage of a power system by comparing an average value of all the average values of voltages, each at each of a plurality of ground points of the system with a set voltage, and controlling the tap switching of an on-load tap changing transformer by the compared result.
CONSTITUTION: The end voltages of the loads 3a, 3b in a power system are input to an input converter 12, and digitally converted voltages are input to a voltage regulating relay 13. The relay 13 calculates a time average voltage within a predetermined time for each input load terminal voltage, and then calculates an average value (whole average voltage) of all the time average voltages. The obtained whole average voltage is compared with a preset voltage, and if the whole average voltage is larger than the set voltage, a down command for executing the tap change for reducing the voltage with respect to an on-load tap changing transformer 9 is output, while if the while average voltage is lower than the set voltage, a rise command signal is output.
